You do not need any additional public IP addresses. The remote site will operate on private addresses as your existing site does (using a different IP subnet). What you need is a link between your two private networks.
In the past, you would have used a leased line to connect the two private sites. This is still an option if there is a supplier in your area, but they can be expensive. Another option is VPN (Virtual Private Network) which emulates a leased line. Instead of having a dedicated connection between the sites, you use the Internet. A "tunnel" is created through the Internet between your two sites. Data using this route is encrypted and encapsulated so that it crosses the Internet securely.
At each site you have a DSL router whih is capable of hosting a VPN site to site connection. Normal Internet traffic uses this router as you do at present. Traffic which is addressed to the other private LAN is intercepted by the router and is encrypted and encapsulated before it sent. This traffic is tunnelled through the Internet to the VPN router at the other site.
Encapsulation is the process which enables the tunnelling. After the whole packet is encrypted it is encapsulated (ie given a new header). This new header has the public IP of the destination router. The encapsulated packet goes through the Internet to the router at the other site.
The two sites behave just like any two subnets connected by an IP router (a slow one in this case). Once the site to site link is in place machines in site A can directly contact a machine in site B and vice versa. You can then modify your DNS and Active Directory (if you use a domain) as you would in any routed network.

Can someone help me in this?
Our company is opening a new Branch office that is 100 miles away from the
main office...All our servers are Windows 2003 and all our clients use XP
Pro. Both location have a DSL connection to the internet. We do not have a
static (Public) IP address for the company..just a connection to the internet
through DSL..
How do I connect both location together so we can share files and internet
connection?
What are the requirements? e.g Do we need to lease our own IP address? Do we
need 2 IP address or just one for both sites? do we need a router at each
location?
PLEASE show me in steps like 1 2 3 what to do A-Z
Thanks for help
